The HK-18854-L2 Automatic Oil Particle Counter (Benchtop Type) complies with the requirements of standards such as GB/T 18854 and ISO 11171. It is developed based on the light blockage (light shading) method counting principle and fully conforms to military standards, national standards, and international standards. It can provide fast, accurate, reliable, and repeatable test results as well as complete contamination monitoring and analysis reports. It is suitable for testing the particle contamination level of hydraulic oil, lubricating oil, fire-resistant oil, insulating oil, turbine oil, and other oils. It can be widely used in fields such as aviation, aerospace, electric power, petroleum, chemical industry, transportation, ports, metallurgy, machinery, and automobile manufacturing.
